Australia's National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) has released Woodside's Scarborough Offshore Project Proposal (OPP) for public comment. The Scarborough gas resource, is located approx. 375 kms off the Burrup Peninsula, and forms part of the Greater Scarborough gas fields, comprising the Scarborough, North Scarborough, Thebe and Jupiter gas fields.
Woodside Energy, is proposing to develop the gas resource through new offshore facilities. These facilities are proposed to be connected to the mainland through an approx. 430 km trunkline to an onshore facility. Woodside’s preferred concept is to process Scarborough gas through brownfield expansion of the existing Pluto LNG onshore facility (Pluto Train 2).
The proposed offshore development, referred to as ‘Scarborough’, targets the commercialisation of the Scarborough and North Scarborough gas fields, through the construction of a number of subsea, high-rate gas wells, tied back to a semi-submersible floating production unit (FPU) moored in approx. 900 metres of water close to the Scarborough field.
The proposed development of Scarborough is an integral part of Woodside’s Burrup Hub vision for a regional gas hub which will secure economic growth and local employment opportunities for Western Australia. In addition to the development of the Scarborough and North Scarborough fields, the Thebe and Jupiter gas fields provide opportunities for future tieback to Scarborough infrastructure. As the proposed export trunkline route crosses the Carnarvon Basin, in close proximity to other undeveloped fields, Woodside is also engaging with other resource owners to explore opportunities for future development.
Woodside is targeting a final investment decision in 2020 and for start-up in 2023. Achieving these milestones is subject to all necessary joint venture approvals, regulatory approvals and appropriate commercial arrangements being finalised. The first drilling phase is targeted in 2020 followed by the installation of the trunkline in 2022, FPU installation in 2023 and phase 2 drilling (potentially including Thebe and Jupiter) in 2025. Decommissioning is expected to commence in 2055.
